T 0 (Lil whom, it may] concern.-

Be it known that I, ADOLPH W'AHLE, a citizen of the United States, and aresident of Davenport, in the county of Scott and State of Iowa, haveinvented certain new and useful Improvements in Mechanical Movements, ofwhich the following is a full, clear, and exact description.

My invention can beapplied to various machines, but is more particularlydesigned to be used in connection with washing-machines, churns, &c. andeffective means for converting a continu ous rotary motion into a rotaryreciprocal movement which is so constructed that when the point isreached by the actuating-gear where the reversing movement takes placeit does not suddenly remove the resistance to said gear and create ajerky movement in the machine, but accomplishes such reversion graduallyand smoothly. This I accomplish by the means hereinafter fully describedand as particularly described, and as particularly pointed out in theclaims.

In the drawings, Figure l is a side elevation of my invention. Fig. 2 isa plan View of the same with the fly-wheel and a portion of thesupporting-frame thereof broken away. Fig. 3 is a transverse verticalsection taken on dotted line 3 3, Fig. 1, looking in the directionindicated by the arrows. Figs. land 5 are diagrammatical viewsillustrating different positions of the drive-gear and driven gear whenat different points in their cycle of movement. Fig. 6 is a detail viewof the drive-gear. Fig. 7 is a detail view showing a plan of the knuckleof the universal joint in the center of the fly-wheel.

In the drawings, A represents a suitable support for my invention, suchas the cover of the tub of a washing-machine or churn, and B representsthe screw-plate of the supporting-frame of said mechanism, which has acentrally-located bearing-boss a, that penetratesdown through said coverA, that has journaled therein a vertically-disposed rotary reciprocalshaft 0. Immediately above bearing-boss a shaft O has secured thereto aplate D, which latter at a suitable distance from Its object is toprovide a simple its center has a concentric segmental series ofupwardly-projecting studs E, whose length preferably exceeds one-half ofthe circle intersecting the centers of said studs. These studs areengaged first on the side thereof nearest the center of the plate D andthen on the side farthest therefrom by a spur-gear F, which latter ispreferably slightly beveled and is secured on thelower end of thependulous shaft G, that is pivotally connected at a point above and inalinement with the center of the stud F to means that revolve itcontinuously in one direction. The lower end of this shaft G extendsbelow the spur-gear F, and by its position in the elongated bell Handits contact with the outer edge 0 of plate D, struck from the center ofshaft O outside of the series of studs F, said gear F is maintained inproper engagement with the outer circumference of the series of studs Eand by engagement with the grooved guideways (Z, which the lower end ofshaft Gr enters as it approaches the ends of the series of studs E, ismaintained in engagement with the inner circumference thereof. The endportions in of this guideway are made by making semicircular grooves insaid plate, that are struck from thecenter of the end studs of theseries E, and these semicircular end portions are connected by a reversesegmental groove 1 struck from the center of said shaft O. IVhen thelower end of shaft Gr enters the guideways (Z, the spur-gear F isthereby held in engagement with the adjacent end stud of the series Eand its movement controlled so that it swings from its overhead pivotalpoint 'an equal distance in the opposite direction toward shaft C, inwhich position its engagement with the side of said studs E nearestshaft O reverses the motion of plate D and the shaft O, to the upper endof which said plate is secured. IVhen the spur-gear F while inengagement with the inner circumference of studs E reaches and engageseither end stud of said series E, the end of shaft G in the guidewaywill be moved by reason of its engagement with the guide- Way (Z untilits axis is outside of the circle intersecting the centers of saidstuds, whereupon said spur-wheel will engage the outer circumference ofsaid series of studs and reverse motion of the plate D and cause it andshaft C to move in an opposite direction.

The supporting-frame of the machine above the screw-plate B describes aflattened inclined ellipse and consists of two branches 9' 7*, thatextend in opposite directions from the said screw-plate up around theperiphery of plate D to points on either side of an imaginary verticalline intersecting the pivotal center of the upper end of shaft G, wherethey merge into a flattened bell H. The interior chamber of the bell iselongated in a vertical plane at right angles to that intersecting thesaid branches 9* and is of a width corresponding to about the diameterof the shaft G. The shaft G extends up through the open upper end ofsaid bell, and its upper rounded end fits snugly into the socket a inthe under side of knuckle I in the manner of a ball-and-socket joint andis pivoted thereto by atransverse pin f. The mouth of this socket e iswidened slightly and is of such dimensions as to restrict the swingingmovement of shaft G to that required to enable the spur-gear on thelower end of the same to engage first the inner and then the outercircumference of the series of studs E. The exterior of this knuckle isspherical in so far as the making of the socket e in its under side willpermit, and it is provided at points diametrically opposite each otherwith trunnions g g, that are in a plane at right angles to the verticalplane intersecting the axis of the pin f. These trunnions are journaledin open bearings made in the edges it of the the central opening inwhich the knuckle 1 is seated and journaled, which central opening ismade in the depressed central portion j of a horizontally-disposedbalance-wheel J. The under edge of the depressed central portion of thefly-wheel J is rabbeted to form aseat therein for the circular flange K,projecting horizontally from the upper edge of the bell H, to enter. Thefly-wheel J is supported and has bearings upon the upper flanged edgesof the bell and is prevented from accidental displacement therefrom bythe boss of the spurgear F coming in contact 'withthe lower edge of thebell, which lower edge prevents the knuckle I from working out of itsseat.

From the foregoing description it will be apparent that as the pendulousshaft G can only swing in a vertical plane at right angles to thevertical plane in which the upper portion of the branches of thesupporting-frame B are in and in a plane at right angles theretointersecting the center of shaft C the engagement of the spur-gear onthe lower end of the same with the segmental series of studs E willresult in the rotary reciprocal movement of the plate D and the shaft C.In this connection it is desired to call attention to the fact that theguideway at the points intersected by the circle intersecting thecenters of the studs E will be deeper than at other points along thelength of the said guideway, so as to permit of the shaft Gr swingingtoward or from shaft 0 while circling around the end studs of series E.
